> google dns解析的一个ip是被联通 屏蔽的。
這句話是什麼意思呢?
autoddvpn在ddwrt設定當中,所有DNS解析都走8.8.8.8 and 8.8.4.4
而經過VPN建立之後,連往這兩個IP也是透過VPN安全傳送的,理
論上只要VPN通了就無法干擾對google DNS的解析才對。
我想確定:
1) 你的ddwrt路由器是否設定DNS為8.8.8.8 and 8.8.4.4
並且關閉「为DNS使用DNSMasq」這個選項。詳見
http://code.google.com/p/autoddvpn/wiki/HOWTO
2)autoddvpn跑起來之後 traceroute
8.8.8.8的輸出結果,是否第二hop就是你的VPN gateway?
3) 你發現哪一個網站無法正確DNS解析?
請盡量提供給我訊息。

iTunes会根据访问者的不同返回不同的IP,而通过google
dns返回的IP是被联通屏蔽的。但openDNS返回的ip就没有问题
具体参看
http://www.google.com/search?hl=en&newwindow=1&client=safari&rls=en&q=google+dns
+itunes+墙&aq=f&aqi=&aql=&oq=&gs_rfai=
1)设置的 8.8.8.8 and 8.8.4.4 and 4.3.2.1(也是google
dns),关闭了DNSMasq
2)我设置的 ×.x.x.0 返回的是 x.x.x.131
前三位都是一样的,我按照 issue 17 的说明设置最后一位是
0,现在也上的很正常,必须跟traceroute的一样么?
3)不是不正确解析,而是正确解析的ip,是一个被联通屏蔽��
�ip。墙太变态了,我这边是北京,可能算重灾区吧 :D
现在用OpenDNS中。

我看了一下,貌似有人說聯通屏蔽了Akamai CDN
http://twitbrowser.net/blog/?p=1863
不過理論上應該不會有影響才對,因為:
1) ddwrt透過VPN跟google DNS請求解析, google DNS返回Akamai節點
2) Akamai節點如果在國外的話,ddwrt同樣會走VPN跟國外節點溝通
除非Akamai節點在國內,這樣聯通屏蔽是有可能的,或者google
DNS本身解析有問題,不然我實在看不出為什麼會連不上。
可能需要先知道iTunes使用哪一個域名才行。

我對這個issue很感興趣, 剛剛看到了這篇
http://qingbo.net/blog/post500-issue-of-mac-software-update.html
於是稍微研究了一下,對北京網通DNS查詢swcdn.apple.com
macbook:~ macbook$ nslookup swcdn.apple.com 202.106.196.115
Server: 202.106.196.115
Address: 202.106.196.115#53
Non-authoritative answer:
swcdn.apple.com canonical name = swcdn.apple.com.akadns.net.
swcdn.apple.com.akadns.net canonical name = swcdn.apple.com.edgesuite.net.
swcdn.apple.com.edgesuite.net canonical name =
swcdn.apple.com.edgesuite.net.globalredir.akadns.net.
swcdn.apple.com.edgesuite.net.globalredir.akadns.net canonical name =
a950.cn.w.tl88.net.
Name: a950.cn.w.tl88.net
Address: 60.210.17.19
Name: a950.cn.w.tl88.net
Address: 60.210.17.18
注意,解析過程CNAME給tl88.net 了, 最後獲得的IP 60.210.17.xx
是聯通的國內IP
繼續測試對google dns and opendns解析
macbook:~ macbook$ nslookup swcdn.apple.com 8.8.8.8
Server: 8.8.8.8
Address: 8.8.8.8#53
Non-authoritative answer:
swcdn.apple.com canonical name = swcdn.apple.com.akadns.net.
swcdn.apple.com.akadns.net canonical name = swcdn.apple.com.edgesuite.net.
swcdn.apple.com.edgesuite.net canonical name =
swcdn.apple.com.edgesuite.net.globalredir.akadns.net.
swcdn.apple.com.edgesuite.net.globalredir.akadns.net canonical name =
a950.gi3.akamai.net.
Name: a950.gi3.akamai.net
Address: 96.17.8.162
Name: a950.gi3.akamai.net
Address: 96.17.8.146
macbook:~ macbook$ nslookup swcdn.apple.com 208.67.222.222
Server: 208.67.222.222
Address: 208.67.222.222#53
Non-authoritative answer:
swcdn.apple.com canonical name = swcdn.apple.com.akadns.net.
swcdn.apple.com.akadns.net canonical name = swcdn.apple.com.edgesuite.net.
swcdn.apple.com.edgesuite.net canonical name =
swcdn.apple.com.edgesuite.net.globalredir.akadns.net.
swcdn.apple.com.edgesuite.net.globalredir.akadns.net canonical name =
a950.gi3.akamai.net.
Name: a950.gi3.akamai.net
Address: 208.50.77.88
Name: a950.gi3.akamai.net
Address: 208.50.77.94
都沒有很特別的CNAME記錄,而解析IP也在國外,實際traceroute發
現也會透過autoddvpn走VPN連往該節點。
因此我猜測:
1)
你的iTunes可能在使用autoddvpn之前就已經有聯通的解析cache了,
這個cache可能已經存在iTunes裡面或OS裡面
2) 或許你可以試試看,在autoddvpn+google DNS撥上之後,清除local
OS dns cache,甚至電腦重開機看看,也許就解決了。
當然如果你想繼續使用OpenDNS也是OK的。

使用cleanMyMac清除了所有缓存,重启,现在 swcdn.apple.com
返回的是 63.150.131.164 ,美国ip,问题fix。
thank you
